Table not found error while using PostgreSql in Spring boot Data JPA Rest API - spring-boot

Question

I am developing simple application using spring-data-rest-using-spring-boot. I am using PostgreSQL as back-end database. Below is my Code.
Class - DemodatarestApplication.java
package com.example.data.rest.demodatarest;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import com.example.data.rest.demodatarest.model.StudentDataRestRepository;
#SpringBootApplication
public class DemodatarestApplication {
#Autowired
StudentDataRestRepository repository;
public static void main(String[] args) {
SpringApplication.run(DemodatarestApplication.class, args);
}
}
Model Class - Student
package com.example.data.rest.demodatarest.model;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;
import javax.persistence.Table;
#Entity
#Table(name = "Student", schema="public")
public class Student {
#Id
#GeneratedValue
private Long id;
private String name;
private String passportNumber;
public Long getId() {
return id;
}
public void setId(Long id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getPassportNumber() {
return passportNumber;
}
public void setPassportNumber(String passportNumber) {
this.passportNumber = passportNumber;
}
public Student() {
super();
}
public Student(Long id, String name, String passportNumber) {
super();
this.id = id;
this.name = name;
this.passportNumber = passportNumber;
}
public Student(String name, String passportNumber) {
super();
this.name = name;
this.passportNumber = passportNumber;
}
#Override
public String toString() {
return "Student [id=" + id + ", name=" + name + ", passportNumber=" + passportNumber + "]";
}
}
Repository Interface - StudentDataRestRepository
package com.example.data.rest.demodatarest.model;
import org.springframework.data.repository.PagingAndSortingRepository;
import org.springframework.data.rest.core.annotation.RepositoryRestResource;
#RepositoryRestResource(path = "students", collectionResourceRel = "students")
public interface StudentDataRestRepository extends PagingAndSortingRepository<Student, Long> {
}
Application.properties

But I am getting below error . Not able to understand from where it takes "student" instead of "Student" table name. I have created table Student in PostgreSQL.
Below is the error

Answer 1

Renaming the Student table to student (lower-case) both in Database and Entity class should fix the problem.
#Entity
#Table(name = "student", schema="public")
public class Student {
